DataHub

Project12.8K

Self-hostable metadata platform for cataloging data, discovering assets, and tracing lineage.

Replaces
GitHub

What you can build

  • Build a connector that takes records from an internal inventory JSON export, maps them to DataHub metadata, and ingests the resulting catalog entities.
  • Build a checker that takes changed dataset URNs, queries lineage, and outputs a reviewable list of downstream assets.
  • Build a script that takes required dataset URNs, checks catalog ownership, and writes a CSV of assets without an owner.
  • Build a linter that takes glossary terms and asset descriptions, then outputs assets whose documentation may omit expected terms.
  • Build a CLI that takes a catalog search query and saves matching asset names and descriptions as a Markdown handoff.

Try this prompt

Build a small Python release-impact checker using DataHub's documented lineage capabilities. Take a CSV of changed dataset URNs, query downstream lineage, and write a reviewable CSV of affected assets. Preserve the input file, report missing assets clearly, and include sample input and output. Keep credentials out of reports and document the required DataHub configuration.

Get started

  1. Choose a deployment path

    The README distinguishes self-hosted DataHub OSS from the separate managed DataHub Cloud service. Follow the OSS quickstart for the self-hosted path: https://docs.datahub.com/docs/quickstart

  2. Check local requirements

    The README lists Docker with 8 GB RAM and Python 3.10+ for a local run. Consult the official quickstart for setup details.

  3. Plan metadata ingestion

    Use the official metadata-ingestion CLI guide for supported sources, or the custom ingestion source guide when adapting an internal source: https://docs.datahub.com/docs/metadata-ingestion/cli-ingestion

License & notes

Apache-2.0DataHub OSS is Apache 2.0 and may be used commercially subject to the license terms. You provide and pay for the infrastructure you operate and any external services you choose to use. DataHub Cloud is a separate managed offering; the supplied sources do not provide pricing. The README lists Docker (8 GB RAM) and Python 3.10+ for a local run.

  • A local run requires Docker (8 GB RAM) and Python 3.10+; self-hosting also requires infrastructure you operate.
  • Catalog coverage depends on the metadata you ingest. DataHub Cloud is a separate managed offering from the Apache-licensed self-hosted edition.
